Abstract: PURPOSE:To suppress the increase in size and decrease internal resistance by making the surface of a metal form itself into a rough surface after performing pretreatment at an electrode plate and bonding thermally under fusion the electrode plate to a current collector by the use of a hot presser. CONSTITUTION:An electrode plate 3 is obtained by making copper, aluminum, zinc or a carbon sheet and the like form itself into a thin plate like shape. In the case of a metal sheet, a surface that is in contact with a current collector 2 is manufactured in a mat face, for example, by dipping it in a solution having the prescribed concentration of nitric acid and dilute sulfuric acid and the like, i.e., corrosives of metals and pretreatment is performed after washing. Then, for example, the current collector 2 and electrode plate 3 are placed on a melt-bonding prevention plate 11 of aluminum by the use of a hot presser and both of them are tightly bonded under fusion by performing prescribed pressurization and heating. In this way, electric charge from an electrode compact 1 acting as a polarizable electrode is received by the current collector 2 that is closely in contact with the above electrode compact and is introduced into the electrode plate 3 that is thermally bonded under fusion. Thus an electric double layer capacitor in which contact resistance between the current collector 2 and electrode plate 3 is low is obtained.

Title: Method of compensating error in measuring circle or arc and meter with compensator
Inventor: TOKANO KUNIO
IPC: G01B21/20
Filed: 1978-07-12
Abstract: PURPOSE: To compensate the position of a measuring element thereby to make it possible to accomplish the accurate measurement by locating the position, where the value obtainable from a fine meter assumes its maximum, while moving the measuring element at a right angle with respect to the radial moving direction.  
     CONSTITUTION: The guide center of the rotations of the measuring element 21 of a fine meter 2 is aligned as much as possible with the center of the arc of a test piece 6. Under the condition having the element 21 contacting with the plane to be metered, the element 21 is moved at a right angle with respect to the radial direction by a fine adjustor 4. If the contact of the element is positioned at a point A, the direction of the contact whit respect to the rotation guide center of the element is always aligned with the magnification calibration direction irrespective of the size of the radius of curvature of the test piece. As a result, the error of the contact point of the element is compensated. After this compensation, if the element 21 is moved on the basis of the guide center, the accurate circle and arc measurements can be performed.
